On a side note - hoping the MSI 290X Lightning or Galaxy 290X HOF turn out to be power houses and my AX850 can handle it. Guessing mid-January.
Any word on Matle release with BF4 yet? We're on the end of Dec now and thought it would have provided at least some reviews.
^^This could explain your problem. Check your sleeved extensions, especially the PCIe power connector for bad contact.
Thankfully nothing melted or burn. I've seen a lot of things melted in my life. In all occasions, my computers survived. One time my computer got power surge because of lightning that day. That scary one. I can see sparks in the casing. Only PSU burn though.

Depends on the quality of the component they use in non-reference design, especially VRM. So far I see the only limit on reference design is temp. Also, it seems water cooling doesn't increase overclock capability. What max clocks you get on air, it will be the max overclock on water. Maybe a little bit stable than on air. I don't see non-reference design can change all these though except running much cooler.
With reference design, water cooling them are good idea. Fan at 50% with two cards still running silently than my reference 5870 card at the same speed. However, I need to run the fan at least 70% - 80% speed since ambient here pretty high, 32 - 34C (indoor), to keep temp below 90C. 70 - 80% with two cards, really, really loud. Running fan at default speeds not bad though. Temp max out at 94C & the games still running smooth though.
BTW, based on track record, for example ASUS, does direct cu cards overall better than reference cards?
